CME Analysis Information (for CME activity ID: 2025-06-06T09:36:00-CME-001)
Catalog: M2M_CATALOG
Data Level: 0 (0=real-time, 1=real-time and checked by supervising forecaster, 2=retrospective science level data analysis)
Use as primary measurement: true
Measurement Technique: Plane-of-sky

Detecting Instruments:

STEREO A: SECCHI/COR2

Image Type: running difference
Speed (km/s): 543.0
Speed measured at height (Rs): 10.0
Type: C
Direction (LON/LAT in HEEQ): None Entered / 19.0
Half Angular Width (degree): 10.0
Minor Half-width (degree): None Entered
Tilt (degree): None Entered
Time@21.5: 2025-06-06T15:31Z
Info/Session URL: None Entered
Note:

Plane-of-sky measurement was using four frames of STEREO A COR2 imagery, before the leading edge becomes too diffuse to track. After several attempts, the leading edge of this CME is not reliably trackable in SOHO LASCO C3, C2, or in GOES CCOR-1; the leading edge is too diffuse or is not discernable in the imagery. The leading edge is visible and reliably trackable for a few frames in STEREO A COR2.
